2R regenerator based on high non-linear dispersion-imbalanced loop mirror

Abstract A 2R regenerator is demonstrated for the first time based on high non-linear dispersion-imbalanced loop mirror (HN–DILM). Theoretical results show that the increment of the extinction ratio and Q -factor could be achieved by using the HN–DILM when carefully choosing the input peak power. The receiver sensitivity of a noise-loaded 10 Gbit/s signal is improved by 2.9 dB by using the 2R regenerator.
